With these features, the Growatt Ark HV Battery can provide a high-capacity, high-voltage, high-safety, high-reliability, and high-flexibility solution for the solar energy storage and utilization.
The process of using the Growatt Ark HV Battery can be divided into three main steps: installation, operation, and maintenance.
Installation
The first step of using the Growatt Ark HV Battery is installation. In this step, the battery is mounted on the wall or the floor, and connected to the solar inverter and the power grid. To do this, the user or the installer should:
• Choose the appropriate location and orientation for the battery, according to the instructions of the manual. The battery should be installed in a dry, ventilated, and shaded place, away from heat sources, flammable materials, and corrosive substances.
• Mount the battery base on the wall or the floor, using screws and anchors, and make sure that the base is level and stable.
• Place the battery module on the base, and align the connectors and the buckles of the module and the base, and snap them together.
• If more than one battery module is needed, stack the additional modules on top of the first module, and align and snap the connectors and the buckles of the modules.
• Connect the communication cable and the power cable of the battery to the corresponding terminals of the solar inverter, and ensure that the wiring is correct and secure.
• Connect the power cable of the solar inverter to the power grid, and ensure that the wiring is correct and secure.
• Turn on the power switch of the battery and the solar inverter, and check if the battery and the solar inverter are working properly and synchronously.
Operation
The second step of using the Growatt Ark HV Battery is operation. In this step, the battery stores and supplies electrical energy, according to the commands of the solar inverter and the user. To do this, the user should:
• Monitor the operation status of the battery and the solar inverter, using the display screen or the monitoring system, and check if the battery capacity, voltage, current, temperature, and mode are normal and consistent.
• If the solar inverter detects that the solar panels are generating more power than the load demand, the solar inverter will send a command to the battery to charge, and the battery will receive the excess power and store it in the battery cells.
• If the solar inverter detects that the solar panels are generating less power than the load demand, the solar inverter will send a command to the battery to discharge, and the battery will release the stored power and supply it to the load.
• If the user wants to operate the battery manually, the user can use the remote control or the app to switch the battery mode, and choose the charge, discharge, or standby mode, according to the user’s preference and the grid condition.
• If the battery encounters an abnormal situation, such as overcharge, overdischarge, overcurrent, short circuit, or overtemperature, the BMS will activate the protection function, and cut off the power supply, and alarm the user.
Maintenance
The third and final step of using the Growatt Ark HV Battery is maintenance. In this step, the battery is inspected, cleaned, and repaired regularly, to ensure its normal and reliable operation. To do this, the user or the installer should:
• Turn off the power switch of the battery and the solar inverter, and wait for the battery and the solar inverter to cool down.
• Check the appearance and the performance of the battery and the solar inverter, and look for any signs of wear, damage, or leakage.
• Clean the surface and the interior of the battery and the solar inverter, and remove any dust, oil, or corrosion, using a soft cloth and a mild detergent.
• Replace the fuse, the connector, or any other parts of the battery and the solar inverter, if they are damaged or worn out, using the original or the compatible spare parts.
• Turn on the power switch of the battery and the solar inverter, and test the operation of the battery and the solar inverter, and check if they are working properly and synchronously.
Conclusion
The Growatt Ark HV Battery is a high-quality and high-efficiency battery system that can meet the diverse needs of solar energy users. The Growatt Ark HV Battery has a simple and flexible product process that ensures its high performance, reliability, and safety.
